TO ALL WIIOMIT MAY CONCERN: y p

Be it hnown that I, GEORGE MERRITT, of the city and county of New York, in the State of New York, did inventa new and useful Pencil-Point Protector, for kwhich' invention Letters Patent of the United States were issued to me'on the 5th day of March, 1867, and numbered 62,555, and that having-been advised by counsel learned in the law that said 'Letters Patent -are inoperative., and invalid by reason ofl a defective specification, I have applied to the Commissioner of Patents to issue to me new Letters Patent for said invention under an amended specification; and *I- do hereby declare that the following is a full and exact description thereof.

My invention is adapted to fit upon the end of a connnon Alead pencil, and to protect the point freni injury. I combine with the hard casing, which fornisthc body ofthe protector proper, a rubber covering adapted to serve for erasingl lines ,fand thevwhole may be produced cheaply, and is adapted to serve in a very convenient and eilieient manner. When the pencil is in use thepro'tcctor may be fitted, as is usual with other protectors, upon the opposite end of the lead pencil. I will `Erst describe What I consider the best means of carrying out my invention, and will afterwards designate thepeints which I believe to be new. The accompanying drawings form a part of this specification.

Figure 1 shows the form in which the sheet brass or other` metal is first cut from a broad sheet of metal.

Figure 2 is a side elevation of the protector after it has been bent into the complete form and encircled by the spring. I 4

Figure 3 represents the same after the rubber eraser has been added. This viewr is taken at right angles to vthat in iig. 2,

Figure 4 is a longitudinal section on the line S S in iig. 2.

Figure 5 is a cross-section on theline T T in fig. 2.

Similar letters of reference indicate like parts in all the g'ures.

A is a central, swelled/end, which applies opposite to the point of the lead pencil M. A1 and A2 are extensions therefrom, which are struck, by dies or otherwise, into the form of arms or wings extending,r parallel to each other, as represented. The part A Ax yA2 is formed from one'piece of hard brass. The form in which the piece is first out is indicated in iig. l. .The ferm which it finally assumes after having been shaped by the dies `is indicated in iig'. 2. B is a nearly complete ring of hard brass wireor other elastic metal, It is applied upon theA protectorin the manner represented, and is received between two swells or beads struck up, as represented on the parts Al A2. This partial band Btcnds to hold the extremities of the wings A1 A2 close together, but will yield by its elasticity and allow them to open to receive a large pencil, or to close and t with tolerable tightness upon a pencil which is a little smaller than the average. The-wood of lead pencils is usuallyso uniform in diameter that it is practicable to make one .of my pencil-point protectors tit on all ordinary pencils C1 C2 are deep indcntations produced byfdies. At these points the metal of the wings A1 A2 is forced in and considerably beyondthe lgeneral interior surface of the protector. 'lliese indentations form stops or shoulders,

against which the conical or' deeper port-ion of the pencil, supposed to be pointed in the ordinary manner, is

rested when it is forced into the-protector, D is a rubber piece made in anannular form, but somewhat smaller than the interior of the metal portion A Al A2. In being forced on it is extended, and retains its place by embracing tightly the exterior of'the ymetal portion. ,Its hold upon the metal portion nia-y be increased, it" desired, by lforming a number of indentations and projections on the exterior o' the portions .A1 A2, but I do not consider it usually necessary. Its exterior periphery may be deepen-as represented, and formed in a square er other desired figure near the end. The elasticity of this rubber tends to hold the wings A1 Azptogethcr. l`It may serve with some success as a substitute for thel partial ring B, but I prefer to use both. The cxtreme ends oi the wings A1 A2 are scalloped and flared outward, as indicated at al a2, '.lhc scalloped ferm allows the edge of the metal'to bc flared with facility, and the lHaring form allows it to receive the tapering portion ci a largo pencil without arresting its motion or abrading the surface. But the motion of thcpencil irni'ard into the protector is always arrested on striking the stops C C2, and thcse'stops are at asuilicient distance from the end A to preserve the pointof the pencil, whenrpointod in the ordinary manner, from contact with any ci' the surfaces.

y. L. lhere 4are many modifications-ef form which may be applied to my protector. Thus, for example, the uulentations C102 may he mede' more sharp endl-eiiioient by partially cutting the metal 'et or neer these points, and

i bending inward the eut port-ion g, or nga-in, :tveoinplete groove may 'be struck lquite around the entire protector;

or only one of the stops, C1 for example, may beused instea-d of two or''agein, the entire outer end of the metallic portion ofthe protector-by which I' meen what was originally the eentral portionA--zind' the adjusting ends of tho Wings'Al A2 may be made of less ,die1neter,when the artiele'is iinished, tliftn the portion around which the spring B is applied, I propose to' ine-kevthe swelled endA serve its u sea-1 when desired, and to stamp,

or otherwise produce enit, n stalr or other convenient device, in order to use the seal upon thin wax. The rubberportion D muy be slipped down from the end, or. may be removed altogether. It is not essential that the spring-Bhe mede of n partial ring of wire; it may be mode of eeeifnplete ring of India rubber, or any other substances, if desired. My protector may he used without the eresive heed D, and still afford e' portion of the i advantages due to my invention, The rounded form of the end A allows the protector to be more easily inserted in the erosive hea,d and, in case it he used without the seid head, makes it. more smooth and more convenient for carriage in the pocket. V

Having now fully described nay invention, what I claim` as new in pencil-point protectors, and desire te secure by Letters Patent, is es follows:

1. I claim a. peneilrpoint' proteeter,innrlewith two or rn'ore wings A1 A2, adapted to fit on the enolosedpeneil i M, substantially as herein speciiied. V Y Y 2. Ieleim the metal piece A A A2,'and the spring B, adapted to operate together upon the end of an ordinary wood pencil, substantially as and for the purpose herein specified. i

3. I claim the combination of :i rubber eraser, D, with the metallic portion, so as to give the proper erasive property to the exterior, and also to contribute by its'eontraetile force to the clasping of ,the metallic portion upon the wood of the contained pencil, substantially as herein specified,

:l 4. I ola-im the scalloped and Hering mouth a1 e5' on the nietallie peneil-point protector, substantially as herein speeified. p i A 4 In testimony whereof I hereunto set my hund in presence of two subscribing witnesses.
